Newton's third law says:
"<span>For every action, there is an equal and opposite reaction. ".
So, the force that Tom does on the sister is equal to force the sister applies on Tom:
</span>
<span>where the label "t" means "on Tom", while the label "s" means "on the sister".
From Newton's second law, we also know

Answer:
Column X. Tangential Speed
Column Y. radius
Explanation:
The equation for centripetal acceleration is
= v² / r
Where v is the tangential velocity of the body and the radius of curvature.
To analyze this equation you must place the tangential velocity in one column and in the other the turning radius
Let's check the answers
Column X. Tangential Speed
Column Y. radius
This is the correct answer.
